2. 1. Active Stabilization of Thermoacoustic Oscillation

   Author : Martin Ansbjerg Kjaer; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; subspace–based identification; fuel actuation; thermoacoustic instability; LQR; Active control;

   Abstract : Combustion processes serve as important sources of energy for both power generation and for transport, ranging from large scale power stations to micro turbines and aeroplane engines. Lean premixed combustion offers a potential to reduce the emission levels, but suffers from instability problems which can be overcome by the use of active control. READ MORE

4. 2. The Pneumatic Hybrid Vehicle - A New Concept for Fuel Consumption Reduction

   Author : Sasa Trajkovic; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VVA; Regenerative; Air-motor; Compressor; Pneumatic; Hybrid; Vehicle; Electric Hybrid; Drive Cycle; GT-Power; Simulink; FPGA;

   Abstract : Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional internal combustion engines (ICE) could be saved, the fuel economy would improve. READ MORE

5. 3. HCCI Operation - Closed loop combustion control using VVA or dual fuel

   Author : Petter Strandh; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motorer; framdrivningssystem; Motors and propulsion systems; applied thermodynamics; Model Predictive Control; System Identification; HCCI; Closed Loop Combustion control; termodynamik; Termisk teknik; Thermal engineering; Ion Current;

   Abstract : The current technology within combustion engines have the possibility of handling the more stringent legislative demands on combustion engines. However the required solutions are getting more expensive and technically challenging. READ MORE

6. 4. Model-Based Optimization of Combustion-Engine Control

   Author : Gabriel Turesson; Institutionen för reglerteknik; []
   Keywords : Model Predictive Control MPC ; Partially Premixed Combustion; Pressure Sensor Feedback; Model Based Control; Particle Filter; Multiple Fuel Injections; Gasoline Compression Ignition; Model Predictive Control MPC ; Partially Premixed Combustion PPC ; Low Temperature Combustion; Model Based Control; Multiple Fuel Injections; Pressure Sensor Feedback; Particle Filter; Gasoline Compression Ignition;

   Abstract : The work presented in this thesis is motivated by the need to reliably operate a compression-ignition engine in a partially premixed combustion (PPC) mode. Partially premixed combustion is a low temperature combustion concept, where the ignition delay is prolonged to enhance fuel-air mixing in the combustion chamber before the start of combustion.

7. 5. Towards Energy Efficient Control of Individual Wheel Drive Articulated Vehicles

   Author : Fredrik Broström; Jonas Fredriksson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

   Abstract : The aim of this thesis was to increase knowledge in the area of articulated vehicles and specifically energy efficient traction control. Eletrical propulsion of vehicles has started to be popular due to its versatility and freedom of design. READ MORE
